EWS The correct way to remove or replace your system apps is to compile the OS yourself without them or with replacements.
Some of the apps can't be removed without causing breakage, and if you touch them or compile an OS for yourself with any changes, you shouldn't expect troubleshooting help from GrapheneOS community because GrapheneOS warns users to not touch system apps, and if you compile an OS for yourself with any changes, then it's not GrapheneOS anymore; it's a fork of GrapheneOS.
